The Transmission Company of Nigeria (TCN) has attributed Thursday’s power disruption across Lagos and its environs to a fault on the Benin, Omotosho 330kV transmission line, assuring electricity consumers that engineers are working to restore normal bulk power supply.
In a statement issued on Thursday by its General Manager, Public Affairs, Ndidi Mbah, TCN said the incident occurred at about 8:19 a.m. when the national grid experienced voltage instability that quickly spread across the Lagos corridor.
According to the company, the disturbance led to the loss of some generating stations, transmission line outages, and interrupted electricity supply to Lagos and surrounding areas.
TCN explained that the National Control Centre immediately directed several generating stations to reduce their output to contain the frequency rise, stabilise the grid and prevent further disruption to the national electricity network.
The company disclosed that the Minister of Power, Chief Joseph Tegbe, convened an emergency meeting with the management of TCN and the Nigerian Independent System Operator (NISO) shortly after receiving reports of the incident to coordinate restoration efforts.
It added that the Benin-Egbin 330kV transmission line, which was also affected during the disturbance, has since been restored and is now transmitting bulk electricity.
However, TCN said engineers from its Benin and Omotosho sub-regions are still working to rectify faults on the Benin-Omotosho 330kV transmission line to achieve full restoration of electricity supply to the Lagos complex.
The company expressed regret over the disruption and the inconvenience caused to residents, businesses and other electricity consumers in the affected areas.
TCN assured the public that the Ministry of Power and other relevant agencies were taking all necessary steps to restore the affected transmission line and strengthen the national grid to reduce the likelihood of similar incidents in the future.
The regulatory agency appealed to consumers to remain patient while restoration work continues, promising to provide updates as progress is made.
